Hi, please i need help. Im from Bolivia in South America, my printer is a ROBO 3D R1+ and I had a problem with a stuck extruder so i unemsabled it an cleaned up, after that it was working fine but i noticiced that the big fan on the back of the extruder was not working so i tested with the small fan cable and it worked so i suposed that it was loose or somethig on the board inside. I took off the base to see and it was all fine then y tried to conect the big fan cable to the fan1 on the board and it made a short circuit on the fan 1 and now it doesn´t turn on. A green led blinks twice and thats it. Please help me.
